BUTTON.

Application filed March 10, 1921. Serial No. 451,364.

. land, a subject of the King of Great Britain,

have invented certain new and useful Improvements in Buttons; and ldohereby declare that the following is a full, clear, and exact description thereof.

This invention has reference to the manufacture of those uniform buttons and other like buttons in which the body of the button is formed of compressed leather or horn or other pierceable non-metallic body part furnished with a metallic shank. Heretofore various means have been adopted for fixing the metallic shank to the compressed leather or horn or other non-metallic body part, one method being to employ a U shaped wire shank the-ends of which are spread slightly apart and are forced through holes in a metal back plate and are-spread farther apart in the compressed leather orhorn orv other body part. It is found in'practice however that sometimes these "wire shanks.

pull out as their ends havenot suliicient hold in the compressed leather or horn or other non-metallicbody part of the button. This in the back of the button.

According to my invention I employ a loop shaped button shank which has a multiplicity of prongs preferably four, although I do not confine myself to any particular number, said prongs forming the rays of a star shaped metal blank, said prongs being bent from the center so as to each form approximately the letter U and thus together form a hollow cage like shank, and the ends of the prongs are preferably pointed and turned apart slightly and may be plain, jagged or barbed and these prongs are driven into the compressed leather, horn, or other piercea-ble non-metallic body part of the button so that the end portions of the shanks are embedded in said body part and spread apart and form a good hold in the substance of the button body so that they areprevented from pulling out under the strains to which the buttons are subjected when sewn on the garment. Y v

A metallic back plate with inwardly or outwardly turnedrim adapted to be forced into and be embedded in the substance of the button and pierced for'the prongs of the shank to pass through may be used with said ter and said back plate be fixed together before the rimof the back plate is forced into and therebyfixedto. the leather or other pierceable non-metallic body part. I For full 'comprehension however of my invention reference must be had-to the ac companying drawingsin. which similar referenc'ev characters indicate the same parts and wherein: 1: Figure l is a sectional elevation. of: a leather or other non-metallic button made according to this invention; 'f-This view is taken on lineX X of Fig. 2 which isan inverted plan of said button;

Figure 3 is a plan of the star shaped blank for forming the 'multi-pronged shank of said button; i

l iguree is a planofa modified form. of said-blank; r q

Figure 5 is a sectional elevation of'a modified form of said button;

Figure '6 is a sectional elevation of a further modification of the same, and

Figure 7 is a sectional elevation and plan of a further modification of invention.

A is the compressed leather or other nonmetallic body of the button and B is the multi-pronged shank of the same which in the example illustrated is made from a four rayed star shaped blank. Fig. 3, the prongs or rays 1 of which are bent from the centre 2 so that each opposite pair forms approximately the letter U and thus together form the hollow cage like shank. The outer ends 3 of the prongs 1 are preferably pointed so as the better to penetrate the leather or other non-metallic body A and. their ends are spread apart slightly so that they will still further spread when forced into the leather or other non-metallic bOdy A.

In order to increase the frictional hold or grip of the prongs 1 in the compressed leather or horn or other non-metallic body part A. of the button the end portions of the prongs which engage in the said body part may be barbed, or jagged or roughened, see

Fig. 4, said barbs or the like projecting backwardlyso as nottoretardthe forcing of the yprongs of the shank into the body of the button, but to afford a considerably increased hold in the substance of the button, head against any pressure tending to draw the.

shank out from the main portion of the but ton. The prongs 1 or :the cage like "button,

shank may for additional security pass through corresponding holes pierced in a metallic backplate 5.ovvhich be made With can 3 outwardly turn ed flange 6 (Fig.

I or an inwardly turned flange 7 (Fig.

button-and affords extra 7 multi-pronged shank.

which ifiange when pressed into "the substance of thefibutton further spreadsout- Wardlyor inwardly and thus obtains a firm grip in the a substance of the body A of the security i to the Onas atfu'rthermodification (see Fig. 7) thew-said cage like button shank B may be securecbto the metallic back plate 5 by passing througha corresponding number ot' holes pierced therein and then spreading out Wardly the'ends otzthe prongs on the inner side of :thexbackplateb before the latter is secured ato the'button by being pressedztherein and its flange spread outwardly-=01 in- Wardly-'in:the substance of the button" as above described 1' Whatd claim is'a s follows: I .1; A b utton of a material which will per- Init of a prong being driventhereinto comprisingia body :and a shank secured thereto, said:shankconsistingof a unitary device "havingtwo pairs ofprongs bent to U form, one :pair being disposed'at right angles to the other pair, said prongs being constructed andwarranged, to anchor [in the body when driven thereinto. :2.
